See full explanation in patch #1. It looks like on qcom platforms
we're increasing the number of situations where we need to have
a set of clks that aren't touched by the OS because firmware
wants them for itself. This series introduces a method to do that
by specifying in DT what clks shouldn't be read or written and
then having the qcom clk driver neve register the ones that 
are protected.
